LBJ- II o FliF -ikihnli o 1' Alma 33 I SEES forming a tight joint. These ribs 31 form the carlines of the roof and are turned downwardly as indicated at 32. The interior of the roof peak is provided with a longitudinal central air channel 33, which serves not only to brace and unite the roof plates when they are formed in two sections but is further adapted to permit the air from the fines to be distributed through the cars. The roof plates are riveted to the side plates and corner braces 34 servei'urther to strengthen the car frame.

Within the ribs or carlines 31, we provide apertures 35 which open into the central air channel 33 and may, ii. desired, open. directly into the interior of the car, as indicated in Fig. Apertures 36 in the air channel 33 permit the air to be distributed from end to end of the car. It will thus be seen that the lines which are open at the bottom will permit air to be drawn upwardly at the sides of the car and distributed evenly at the roof, the side stakes and carlines forming continuous fines for this system of ventilation.

The doorways 42 at the sides of the car are closed by sliding doors e4: somewhat in the usual manner.

F or passenger car construction, the ribs are slightly modified in form, the ends 53 being flattened in order to secure same to the outside plate 5%. The ribs 25 will, however be similar in other respects, constituting ventilating lines and supports as above described. These lines may be provided with dampers 55 at the bottom, or may be,

provided with. sliding dampers in the interior of the car.

A full description of the remaining structure of the car will be found in our co-pending application, Ser. No. 613,968, divided from this application and filed March 13th, 1911.

It will be seen that this construction of car besides being neat in appearance will be very strong and durable and will be particularly adapted for carrying such freight as requires ventilation without exposure to or moisture. The car is well adapted for carrying live stock and, for this purpose, apertures for the admission of air may be made in the dues at the interior of the sides ofthc car. For carrying grain, fruit, meat, and the like, this construction of car will eliminatesweating or the accumulation of moisture which is one of the great difficulties heretofore experienced in connection with. the use of metal freight cars. It will also be obvious that for passenger cars, this system of ventilation will aiiord great advantages over any system that can be used in cars of, other types.

. While we have shown the preferred form of construction, it will be apparent that many modifications may be made without departing from the spirit of our invention.

Having thus described our invention, what we claim is,;

1.- In a ventilated car, a series of ventilating flues extending from the lower to the upper edge of the sides, transverse fiues connectingthe side fines over the roof, said fines beingopen at their lower ends, a longitudinal flue in the roof connected with said transverse fines, and a plurality of outlets from each transverse flue and from the longitudinal flue.

In a ventilated car, a series of ventilat ing flues extending from the lower to the upper edges of the car sides, a longitudinal flue in the car roof, transverse flues connecting the side fines in pairs with the longitudinal flue, outlets from said longitudinal flue communicating with the interior of the car, and dampers at the lower ends of the side flues.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
